Patents by Inventor Joseph Weinschenk

Joseph Weinschenk has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Accommodative intraocular lens system
    Patent number: 8012204
    Abstract: A two optic accommodative lens system wherein at least one of the optics is deformable. When compressed by the capsular bag, the two optics press against each other, deforming at least one of the optics. As a result, the interface where the two optics meet changes shape, thereby altering the refractive power of the lens system.
    Type: Grant

  • Correction of chromatic aberrations in intraocular lenses
    Publication number: 20080147185
    Abstract: In one aspect, the present invention provides an intraocular lens that includes a posterior optic and anterior optic. The optics have different chromatic dispersions adapted to cooperatively provide compensation for natural chromatic aberrations of the eye over a wavelength range of interest, e.g., over a wavelength range of about 400 nm to about 700 nm.

  • Incorporation of adsorbents during extraction and/or hydration of hydrogel materials used as ophthalmic devices
    Patent number: 5713460
    Abstract: Disclosed are methods for extracting leachable materials from a hydratable polymer by incorporation of an adsorbent into the solution employed to effect extraction. Suitable adsorbents are characterized as having a higher affinity for the leachable materials than either the hydratable polymer or the solvent employed in the solution. Also disclosed are sealed packages comprising an aqueous solution, an adsorbent and a hydratable polymer in the form of an ophthalmic device.
